IMPROVEMENT IN RECIPROCATING CHURNS.

Specification forming part of Letters Patent No. 165,954, dated July 27,1875 application filed March 2, 1875.

To all whom it may concern:

Be it known that I, DAVID RowLAND, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulimprovement in that class of mechanism intended to give a reciprocatingrectilinear vertical movement to the dash-rod of an ordinary churn.

My invention consists in the peculiar construction, combination, andarrangement of the several parts shown and described, for the purposesof accomplishing the stated object, which construction, combination, andarrangement will be readily understood from the lot lowing description,taken in connection with the accompanying drawings, wherein- Figure 1represents a side elevation of my improved churning apparatus; Fig. 2, atop view of the driving mechanism.

1 first construct a frame, A, which should be strongly made to enable itto withstand the wear, tear, and jamming motion produced by the churningprocess. On a platform, B, and near the middle of this frame, isarranged the driving mechanism, which consists of a large toothed wheel,(1, that meshes into a smaller wheel or pinion, D, secured on one end ofa transversed shaft supported in suitable bearings. Midway on this shaftis placed and secured a fly-wheel, E, and attached to the end farthestfrom the pinion D is a crank, F, connected by means of a link, H, to thelower end a of a long L-shaped lever,J,pivoted at or near its angle to aproper supportiug-post, K, the opposite end or short arm 6 of this leverbeing also pivoted to a short drop-link, 6, connecting to the projectingend of a cross-head, and attached to the vertical dash-rod m of thechurn W, and which cross-head is made adjustable on the dash-rod bymeans of a gib, P, and'biudingscrew S, the dash-rod being held andsupported in its vertical reciprocating movement by the projectors d dofthe frame, through which the dash-rod passes.

The several parts, constructed, arranged, and combined as represented,can be put in motion on turning the large toothed wheel C by means ofits handle T, which, in turn, will impart a rotary movement to thepinion D and its shaft, together with the fly-wheel E and long outsidecrank F, which, being connected bymeans of a link, H, to the lower armof the L-shaped lever J, will produce therein a vibrating motion aroundits pivoted point; the short arm V of this lever being actuated in thesame manner, which, by means of its connection with the cross-head f andits attachments to the dash-rod M, imparts thereto the requisite andproper up-and-down motion, and that in a vertical line.

I claim- V The cross-head f, gib P, and binding-screw S, in combinationwith the short drop-link c and L-shaped lever J, as and for the purposesset forth.
